ON is used to suggest that a book, article, lecture etc is serious or academic, suitable for specialists.

ABOUT is usual when the information given is more general, or the style of communication is more casual.

A book ABOUT Asia is a book for the general public, whereas a book ON Asia is one for scholars.

Compare:

a book ON African history

a book for children ABOUT Africa and its people

a lecture on economics

a conversation about money

an article on British indutrial problems

an argument about strikes
